Banshee vs. Ubuntu Linux on Revenue sharing

"When Banshee, the popular Mono-based open-source media
player was first included by default in the next version of Ubuntu
Linux , Banshee's developers thought this was great news. But, then
Canonical, Ubuntu's parent company decided that they wanted 75% of
any revenue from Banshee's built-in connection to the Amazon music
store-revenue that Banshee was already donating all of to the GNOME
Foundation.

"Now, this isn't a lot of money–As of February 1, 2011
Banshee had raised $3,077 for GNOME–but it was the principle
of the thing. So when Canonical, "concerned with how our [Banshee]
Amazon store would affect their Ubuntu One store." and proposed two
options: "Canonical disables the Amazon store by default (you could
enable it in a few easy steps) but leaves the affiliate code alone
(100% still to GNOME), or Canonical leaves the Amazon store
enabled, but changes the affiliate code and takes a 75% cut.""
